Definitions
- the present invention relates to a process for the preparation of oligo / polythiophenes.
- OFETs Simple structuring and integration of OFETs into integrated organic semiconductor circuits makes possible low-cost solutions for smart cards or price tags, which hitherto can not be realized with the aid of silicon technology due to the price and lack of flexibility of the silicon components. Also, OFETs could be used as switching elements in large area flexible matrix displays.
- All compounds have continuous conjugated units and are subdivided into conjugated polymers and conjugated oligomers depending on their molecular weight and structure.
- a distinction is usually oligomers of polymers in that oligomers usually have a narrow molecular weight distribution and a molecular weight to about 10,000 g / mol (Da), whereas polymers usually have a correspondingly higher molecular weight and a broader molecular weight distribution.
- Da g / mol
- polymers usually have a correspondingly higher molecular weight and a broader molecular weight distribution.
- it makes more sense to differentiate on the basis of the number of repeating units since a monomer unit can certainly reach a molecular weight of 300 to 500 g / mol, as for example in (3,3 "-dihexyl) -quarterthiophene.
- the most important semiconducting poly- or oligomers include the poly / oligothiophenes whose monomer unit is e.g. 3-hexylthiophene.
- a distinction must in principle be made between two processes - the simple coupling reaction and the multiple coupling reaction in the sense of a polymerization mechanism.
- the polymerization in a catalytic cycle is started by the Kumada method (cross-coupling metathesis reaction) using a nickel catalyst (preferably Ni (dppp) Cl 2 ).
- the polymers are generally obtained via Soxhlet purifications of the necessary purity.
- the processes described in EP 1 026 138 and in the further literature are purely laboratory-technical.
- the reaction solution has a concentration of monomers of about 4-6% by weight and thus a maximum product concentration, e.g. for the poly-3-hexylthiophene of 2-3 wt .-%.
- An increase in the production amount takes place only by the enlargement of the approach such. in Example 2 in EP 1 028 136.
- the object of the present invention was therefore to provide a process which at least partially overcomes the disadvantages mentioned and enables the large-scale production of polythiophenes or oligothiophenes with defined average chain lengths and a narrow molecular weight distribution.
- the polymer concentration (at 100% conversion) defined by the concentration of the two solutions means, in the context of the invention, in particular the concentration of polymer which is present or would be present at (in the concrete applications mostly hypothetical) 100% conversion, when the first solution is added completely to the second solution.

- the term "leaving group” is understood in particular to mean any group which is capable of reacting by means of a metal or an organometallic compound to form a thiophene-organometallic compound.
- the at least one thiophene derivative contains at least two different leaving groups. This may be useful for achieving better regioselectivity of the polymer in many applications of the present invention.
- the leaving groups of the at least one thiophene derivative are identical.
- thiophene-organometallic compound is understood in particular to mean a compound in which at least one metal-carbon bond to one of the carbon atoms on the thiophene heterocycle is present.
